ABSTRACT:
An image display device is disclosed that has a simplified structure and is able to display a high quality image of high resolution at low cost. The image display device includes a light separation unit configured to extract a light beam having a predetermined wavelength band from light emitted from a light source; a light valve that controls a light beam incident thereon to form a plurality of sub frames of a target image; and a light path shift unit operable to shift a light path of an output light beam from the light valve having the predetermined wavelength band according to a frame period of the target image to locate one or more sub frame of the target image at different positions from other sub frames of the target image formed by the light valve.
